GASKET.

SPECIFICATION forming part of Letters Patent No. 696,183, dated March25, 1902.

Application filed August 8, 1901. Serial No. 71,308. (N0 lllOdel- T0 allwhom it may concern.-

Be it known that I, JOHN 1V. MCAULIFFE, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and usefullmprovementin Gaskets, of whichthe following is a specification.

This invention has reference to a gasket for the joint between the baseof a Watercloset, the ioor, and the soil-pipe; and it consists in thepeculiar and novel construction of the gasket more fully set forthhereinafter.

The joint between the base of the usually ceramic water-closet and thesoil -pipe is among all the joints required in sanitary plumbing themost important and the most difficult to make. This joint has heretoforebeen usually made with putty. It required much time, care, and skill tomake a good putty joint, and when made the joint was liable to crack bythe trying of the putty.

caused by the absorption of the oil by the floor, whether of marble,cement, or wood. The absorption of the oil also discolored the iioor andwas very objectionable.

The objectof this invention is to facilitate the setting of thewater-closet and the securing of a perfectly-tight permanent joint.

Figure 1 is asectional View of the base of a water-closet, the floor,the soil-pipe, and my improved gasket shown in the position occupied bythem when the closet is being putin place. Fig. 2 is a sectional view ofthe same parts as shown in Fig. l, showing the base of the water-closetin place. Fig. 3 is a plan view of the gasket.

In the drawings, d indicates the soil-pipe, which is usually flanged andrests on the floor b. In most cases the Iioor is marble, cement, ormosaic. The base c of the water-closet forms a Wide annular flangesurrounding the The gasket d projecting nipple extension c.

is formed in part or Wholly of rubber, and consists, in the preferredform, of the annular iiange d of practically uniform thickness,

from which extends the cylindrical collar di, Y

the lower portion d3 of which is of greater thickness than the portionof the collar ad-` joining the annular flange dC An annular depressiond4 is formed on the under side of, the annular flange d', close to thecollar d2, as

veven distribution of the material of the gasket, forming aperfectly-tight joint between the nipple c and the soil-pipe and a tightjoint between the flange of the base and the floor.

As the gasket contains no free oil the base of the closet and the floorare not stained With oil. The yielding material of the gasket secures aneven uniform bearing for the closet.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In a gasket, the combination with the annular iianged', and the cylindrical collar cl2, of the annular depression d4, andthe enlargement d3 on the collar, as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
